analysis of the Desulfovibrio desulfuricans ATCC 27774 genome shows that no cytochrome c-553 is present in this organism, thus the cytochrome c-553 is not a physiological redox partner of FDH and because cytochrome c-553 has a very high redox potentials in contrast to the low redox potentials of TpIc3 it is more likely that TpIc3 is involved in electron transfer from formate |
